How To Tell If Yeast Is Good

The yeast is a living microorganism that is used in baking and brewing. It is responsible for the carbonation in beer and the rise in bread. If the yeast is fresh and has been stored properly, it will be active and produce carbon dioxide. If the yeast is old or has been mishandled, it will not be active and will not produce carbon dioxide.

How To Tell If Yeast Is Good

The best way to determine if yeast is good is to look at its appearance and smell. Yeast that is good for baking will be smooth, creamy, and slightly orange in color. It will also have a slightly sweet smell. If the yeast has an off odor, it is likely bad and should not be used.
